Why We Made ItWe made the SES 7.8 to achieve two things: more speed and more stability. The SES 7.8 embodies the latest SES technologies and includes our newest molded-in brake track and tubeless clincher tire compatibility. The SES 7.8 is wider and specifically optimized to perform best when used with a modern aero frame and large, 25mm tires.

Full DetailsWhen the race is against the wind and the clock the SES 7.8 is optimized for the task. By reducing the trade-offs between aerodynamics, stability, weight, and stiffness, the SES 7.8 carbon fiber aero wheel is the perfect tool for road racing and triathlon alike. The SES 7.8 features front- and rear-specific rim geometries. The front rim is 71mm deep and 29mm wide, while the rear rims is 80mm deep and 27.5mm wide. The dissimilar rim geometries improve the efficiency of the airflow in the system of bike frame and wheels. Because running 25mm tires is now standard, the SES 7.8 was designed with larger tires in mind. Additionally, frame manufacturers are now producing frames that have more clearance between wheel and frame which has opened up the design scope for a wheelset. The SES 7.8 is optimized for these frames. In addition to changes in shape and structure, the SES 7.8 features the latest molded-in carbon fiber brake track texture and is compatible with road tubeless tires.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
